Introduction to WARTSILA LDU-20
LDU-20 Product Overview
The WARTSILA LDU-20 is a dedicated Local Display Unit engineered for real-time status monitoring and data visualization of marine control systems, serving as a critical human-machine interface (HMI) in engine control rooms, propulsion stations, and auxiliary equipment cabins across ferries, offshore platforms, and cargo vessels. As the “visual hub” for Wärtsilä’s core control modules—including the CCM-20 hybrid central controller and UNIC engine management system—it aggregates and presents key operational data such as engine RPM, fuel consumption, valve positions, and battery charge levels in intuitive numeric, graphical, and alarm formats. A standout feature is its 7-inch sunlight-readable color display with anti-glare coating, ensuring clear visibility even in direct sunlight on open bridge decks or poorly lit engine rooms.
